At present, most of the fabrics in our country are divided into knitted and woven. Woven fabrics are fabrics formed by weaving warp yarns and weft yarns perpendicular to each other. Knitted fabrics are made by forming loops of yarn or filaments with knitting needles, and then stringing the loops into each other. Today we will introduce the difference between the two.
"Knitted fabrics and woven fabrics have their own unique characteristics in terms of processing technology, fabric structure, fabric characteristics, and use of finished products due to different weaving methods. Here are some comparisons.
1 basic concepts
Knitted fabric:
Knitted fabric refers to the process of using knitting needles to form loops of various raw materials and yarns, and then connect them to form a knitted fabric. It can be carried out horizontally or vertically, horizontal knitting is called weft knitted fabric, and longitudinal knitting is called warp knitted fabric.
The loop is the smallest basic unit of the knitted fabric, and the loop is composed of a space curve formed by the loop stem and the extension line.
Woven fabric:
Woven fabrics are made of two or more sets of mutually perpendicular yarns interwoven with warp and weft at a 90 degree angle. The longitudinal yarns are called warp yarns, and the transverse yarns are called weft yarns.
Each intersection point between the warp and weft is called the weave point, which is the smallest basic unit of the woven fabric.
2 Fabric weave characteristics
Knitted fabric:
Because the loops are formed by bending the yarn in space, and each loop is composed of one yarn, when the knitted fabric is subjected to external tension, such as longitudinal stretching, the bending of the loop changes, and the height of the loop increases, and at the same time The width of the loop is reduced. If the tension is horizontal stretching, the situation is reversed. Under different tension conditions, the height and width of the loop can obviously be converted to each other, so the stretchability of the knitted fabric is large.
It can extend in all directions and has good elasticity. Because the knitted fabric is formed by hole-shaped loops, it has greater air permeability and a soft feel.
Woven fabric:
Because the place where the warp and weft interweave is somewhat curved, and the moraine is bent in the direction perpendicular to the plane of the fabric, the degree of bending is related to the mutual tension between the warp and weft and the yarn stiffness. When the woven fabric is subjected to external tension, such as longitudinal When stretching, the tension of the warp yarn increases, and the bending decreases, while the bending of the weft yarn increases, such as longitudinal stretching continuously until the warp yarn is fully straightened, and the fabric shrinks in the transverse direction. When the woven fabric is stretched transversely by external tension, the tension of the weft yarn increases, the bending decreases, and the warp yarn bending increases, such as the transverse stretching continues until the weft yarn is fully straightened, and the fabric shrinks longitudinally. The warp and weft will not be converted, which is different from knitted fabrics.
Knitted fabric manufacturers tell you that the warp and weft of the woven fabric have little relationship with the extension and shrinkage, and there is no conversion, so the fabric is generally tight and stiff. To
